I need to add 3 coats of cloth to re-enforce the hull of my boat. I seem to
remember that one should NOT wait 24 hours between each application, or one
would have to sand/grind the surface to wax??? Is that correct, and what is
the best time to lay the second and third coats?

The area is about 4 x 4 inside of the hull, so I can pretty well time the
applications as I please. All help appreciated. Thanks RichG

If the area is workable and you can do it, I would just lay all three
layers at once. Remember, it is easier to draw epoxy up from under
cloth than to drive it down into cloth. Wet out the area good, lay
down cloth, then start wetting out, this makes things much easier. An
average layer of cloth for me goes like this. 80% of the epoxy I will
use for the layer is on the part before I lay in the cloth. For larger
areas I also have a big table with plastic. I wet out the cloth on the
table too, then lay it into the goo. Even then, I paint the table with
a layer of goo, then lay the cloth into it. You can use tacks to hold
it in place temporarily if it is at a bad angle when you put it on the
part. Once you lay the first layer down, wet the next on the table,
lay it on and squegee the excess out and do the third layer. You will
usually end up with a lighter composite, and a lot less work.
